Research on the design of Transfer Equipment Cask for Tokamak Equator Port Plug

The Transfer Equipment Cask (TECA) is a key solution for Remote Handling in Tokamak Equator Port Plug (TEPP) operations. The paper mainly introduces the design of the TECA whose main usage is to complete fusion reactor in transport, dragging and repair work. Firstly, The Air Transfer System (ATS) is discussed, the modular design details of the ATS is presented. Additionally, a 6-DOFs rhombic-like parallel robot capable of being used for docking with minimum misalignment is discussed. Moreover, the Bidirectional Sealing Door (BSD) system and the tractor which is divided into a manipulator and drag mechanism is introduced. Eventually, the preliminary experimental results indicate that the designs of the TECA are feasible and yield realistic applications for the remote handing of International Thermonuclear Experimental Reactor (ITER).
